Product details
Overview
SMA5J8.0C-E3/61 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for high-energy surge protection on signal and power lines. It features a 8.0 V stand-off voltage (VWM), 13.6 V clamping voltage (VC) at 36.8 A peak pulse current (IPPM), and 500 W peak pulse power (10/1000 µs waveform), with AEC-Q101 qualification for automotive electronics.
For engineers reviewing the SMA5J8.0C-E3/61 datasheet, SMA5J8.0C-E3/61 pinout, SMA5J8.0C-E3/61 application, or SMA5J8.0C-E3/61 equivalent, key selection criteria include bi-directional clamping capability, low clamping ratio (VC/VWM = 1.7), RoHS-compliant matte tin terminations, and MSL Level 1 moisture sensitivity rating for lead-free reflow compatibility.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with breakdown voltage (VBR) specified between 8.89 V and 9.83 V at 1 mA test current. Its low incremental surge resistance enables rapid energy diversion during transients induced by inductive switching or ESD events.
The device exhibits a thermal resistance of 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead), supporting reliable operation up to 150 °C junction temperature. It meets JESD201 Class 1A whisker testing and is qualified per AEC-Q101 for automotive under-hood and infotainment applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal line bias margin. |
| VC @ IPPM | 13.6 V - Clamped voltage at 36.8 A peak pulse current; limits downstream IC stress during 10/1000 µs surges. |
| PPPM | 500 W - Peak pulse power handling (10/1000 µs); supports robust protection against ISO 7637-2 Pulse 1/2a/5a transients. |
| VBR min/max | 8.89 V / 9.83 V - Breakdown voltage range at 1 mA; ensures consistent turn-on across production lots and temperature. |
| ID @ VWM | < 1.0 µA - Reverse leakage at rated stand-off voltage; preserves low-power sensor or communication line integrity. |
| TJ max | +150 °C - Maximum junction temperature; enables use in engine control units and powertrain modules without derating. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, bi-directional configuration with no polarity marking. Dimensions: 4.93 mm × 3.99 mm × 2.29 mm (L × W × H), with 2.54 mm lead pitch and matte tin-plated leads compliant with J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional transient conduction path | No functional polarity - either terminal serves as anode or cathode depending on transient polarity; enables single-device protection on AC or differential lines. |
| Case (cathode band absent) | Non-functional mechanical reference | Bi-directional devices omit cathode band marking per datasheet; orientation does not affect electrical behavior. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock - suitable for safety-critical ECUs. |
| MSL Level 1 (260 °C peak) | Enables standard lead-free reflow without pre-baking; eliminates moisture-related popcorning during PCB assembly. |
| Glass passivated junction | Improves long-term stability and reduces parameter drift under thermal stress and humidity exposure. |
| Low clamping ratio (VC/VWM = 1.7) | Minimizes overvoltage exposure to protected ICs - critical for 3.3 V or 5 V logic interfaces with tight absolute maximum ratings. |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting LIN bus transceivers and body control module inputs from load dump and alternator ripple. IC Role / Device Role / Timing Role: Bi-directional clamping element placed between power rail and ground, absorbing ±100 V/500 W transients per ISO 7637-2. Use Value: Prevents latch-up or gate oxide damage in 5 V microcontrollers and CAN/LIN PHYs without adding series impedance. |
Use Scenario: Safeguarding analog outputs of pressure/temperature sensors in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Parallel-connected TVS on 4–20 mA current loop or 0–10 V analog output lines exposed to field wiring surges. Use Value: Maintains signal fidelity below 1 µA leakage while clamping fast-rising transients (<1 ns rise time) to <14 V. |
| Telecom Data Line Surge Suppression | Consumer USB Port ESD Protection |
Use Scenario: Shielding RS-485 transceivers in base station backhaul equipment from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary-level protection on differential pair, coordinated with secondary GDT or polymer PTC. Use Value: Withstands repeated 500 W surges without degradation, meeting ITU-T K.20/21 immunity requirements. |
Use Scenario: Front-end protection for USB 2.0 data lines (D+/D−) in smart home hubs and set-top boxes. IC Role / Device Role / Timing Role: Bi-directional clamp limiting ESD strikes (IEC 61000-4-2 ±8 kV contact) to sub-14 V levels at the PHY interface. Use Value: Low capacitance (typ. 200 pF at 0 V) avoids signal integrity loss at 480 Mbps full-speed USB operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ8.0CA | Same DO-214AC package, identical VWM (8.0 V) and VC (13.6 V), but rated for 400 W PPPM (vs. 500 W). | Lower peak power rating limits suitability for ISO 7637-2 Pulse 5a (load dump) in 12 V systems. | Select SMA5J8.0C-E3/61 when full 500 W surge handling is required; SMAJ8.0CA suffices for lower-energy ESD-only scenarios. |
| ON Semiconductor 1.5SMC8.0CA | DO-214AB (SMC) package (larger footprint), same VWM/VC, rated 1500 W PPPM - higher power but incompatible PCB layout. | Requires board redesign due to 7.11 mm × 6.22 mm SMC footprint vs. SMA's 4.93 mm × 3.99 mm. | Choose SMA5J8.0C-E3/61 for space-constrained designs where 500 W is sufficient; use 1.5SMC8.0CA only when >500 W is mandatory and layout allows. |
Compared with SMAJ8.0CA and 1.5SMC8.0CA, SMA5J8.0C-E3/61 uniquely delivers 500 W surge capability in the compact DO-214AC footprint with AEC-Q101 qualification - making it optimal for automotive and industrial applications demanding high power density and automotive-grade reliability without layout change.

FAQ
What is the polarity configuration of SMA5J8.0C-E3/61?
The SMA5J8.0C-E3/61 is a bi-directional TVS diode with symmetrical conduction characteristics in both forward and reverse directions. It has no cathode band marking, and either terminal functions identically - enabling use on AC signals, differential pairs, or unmarked PCB layouts without orientation concerns. This behavior is confirmed in the Vishay datasheet section "For bi-directional devices use CA suffix" and electrical characteristics table.
Does SMA5J8.0C-E3/61 meet automotive qualification standards?
Yes, SMA5J8.0C-E3/61 is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet under "MECHANICAL DATA" and "THERMAL CHARACTERISTICS" sections. This qualification covers stress tests including temperature cycling, high-temperature operating life, and mechanical shock - validating its suitability for automotive powertrain, chassis, and infotainment systems.
What is the clamping voltage of SMA5J8.0C-E3/61 at its rated peak pulse current?
The clamping voltage (VC) of SMA5J8.0C-E3/61 is 13.6 V at 36.8 A peak pulse current (IPPM), measured using the standard 10/1000 µs waveform. This value is listed in the "ELECTRICAL CHARACTERISTICS" table for device SMA5J8.0CA and directly applies to SMA5J8.0C-E3/61, which shares identical electrical specs and the "CA" bi-directional suffix.
Is SMA5J8.0C-E3/61 compatible with lead-free reflow soldering processes?
Yes, SMA5J8.0C-E3/61 is rated for MSL Level 1 per J-STD-020 with a maximum peak reflow temperature of 260 °C. Its matte tin-plated leads comply with J-STD-002 and JESD22-B102, and the E3 suffix confirms JESD201 Class 1A whisker resistance - ensuring robust performance in standard Pb-free reflow profiles without pre-baking.
How does the breakdown voltage tolerance of SMA5J8.0C-E3/61 impact circuit design?
The breakdown voltage (VBR) of SMA5J8.0C-E3/61 is guaranteed between 8.89 V and 9.83 V at 1 mA test current. This ±5.5% tolerance informs minimum overvoltage margin design: circuits must ensure normal operating voltages remain ≥10% below VBR min (i.e., <8.0 V) to avoid premature conduction, while staying within IC absolute maximum ratings relative to VC (13.6 V).
